General Motors exhibited its alternative-fuel vehicles (AFVs) at the 2002 National Clean Cities Conference and Exposition at the Cox Convention Center on May 12-15, 2002.
Clean Cities is a program sponsored by the U.S. Dept. of Energy that is designed to encourage the use of AFVs and support infrastructure throughout the nation. The Clean Cities program currently consists of nearly 80 coalitions in 39 states.
GM displayed some of its 2003-model-year AFV portfolio, which includes:
- The introduction of a new CNG van cutaway model. This is an edition of the redesigned 2003 GM Chevrolet Express and GMC Savana full-size passenger and cargo vans that operate either with a bi-fuel or dedicated CNG fuel system. Wheelbases are available in 159 inches or 177 inches, and the fuel tanks will hold 20.6 gasoline gallon equivalent (gge) for bi-fuel or 29.7 gge for dedicated CNG. The 2003-model year is the first time GM will offer the dedicated CNG fuel system on the Express and Savana cutaway vans.
- Chevrolet Silverado and GMC Sierra Flexible Fuel E85-powered full-size pickup.
- Chevrolet Tahoe/Suburban and GMC Yukon/Yukon XL Flexible Fuel E85 full-size SUV, powered by the 285-horsepower, 5.3L V8 Vortec engine.
During the general session GM’s Ken Cameron, program executive for research, development and planning for Fuel Cell Commercialization Activities, participated in a moderated panel of experts discussing the “Pathways to a Hydrogen Future.” The panel discussed the likelihood of near-term commercialization of fuel cells and the role natural gas and other alternative fuels play in building a bridge to the future.
Recently, GM announced its shipment of the first fuel cell demonstration vehicle, the HydroGen1, to the California Fuel Cell Partnership for review and evaluation. The HydroGen1 has been used in rigorous field testing around the world and has accumulated more than 20,000 miles.
In addition, Cameron talked about GM’s AUTOnomy concept vehicle, which is designed from the ground up around a fuel cell propulsion system, and combines fuel cells with x-by-wire technology to allow electronic rather than mechanical control of steering and braking.
Also on May 13, GM’s Sharon Dudley-Parham, assistant brand manager for alternative-fuel vehicles, presented and participated in a panel discussion, “Light Duty Alternative Fuel Vehicles: Product Roll-Out.” Items that were discussed included 2003-model-year product production schedules and availability, plus current marketing and promotional initiatives.

Cox Automotive has established a new mobility services unit that combines existing businesses, such as its Flexdrive subscription service, with its acquisition of Clutch Technologies' subscription software platform to deliver fleet management solutions for mobility fleets, the company has announced.

Fleet management professionals who have completed NAFA's Certified Automotive Fleet Manager (CAFM) program typically earn about a 27% higher salary than those who didn't attain the certification, according to a Monster.com survey.

Diesel-powered cargo vans are providing fleet buyers with a lower total cost of ownership than gasoline models, while many diesel-powered trucks aren't recouping the higher acquisition cost, according to a Vincentric analysis.

UPS will implement a new predictive analytics tool later this year designed to analyze details about its logistics network in order to meet the demands of e-commerce shopping and competition from FedEx and Amazon, and better manage its fleet.

“I am thrilled to have been elected by my peers throughout the fleet industry,” said Jozwiak. She continued, “I am looking forward to contributing, learning and growing with this great Fleet industry organization.”

Mercedes-Benz is bringing its A-Class compact sedan to the U.S. market later this year as a 2019 model that will give buyers a new entry point just below the CLA and the first vehicle with the brand's next-generation infotainment system.
